Epidemics,national security,and US immigration policy

What are relationships between epidemics, national security, and US immigration policy? This question is important because it sheds light on transnational or nontraditional security areas, American immigration policy, and a pressing issue for US leaders who have recently faced epidemics such as the West Africa Ebola outbreak that began in 2013. This article answers it and lays ground in the area by reviewing epidemics in world history, using International Relations and Security Studies works to specify dangers of contagions for states, and identifying three general immigration measures that American leaders have utilized from the seventeenth century to the present day to protect against contagions, which are (1) policies restricting entrance of foreigners thought to carry specified diseases, (2) the isolation or quarantining of immigrants with contagious disease, and (3) delegating the President with authority to stop immigration in the event of an epidemic abroad. This study has implications for research and contemporary US immigration policy.     

Is strategic studies narrow? Critical security and the misunderstood scope of strategy

Critical security advocates commonly portray strategic studies as crippled by its narrow focus on Cold War-era military issues, as state-centric and as Western-centric. I argue that this conception of the scope of strategy is flawed and I offer a comprehensive rebuttal by working out the logic of the theories advanced by Carl von Clausewitz and Thomas Schelling. The proponents of critical security overlook the striking expansion of strategy during the Cold War, its longstanding inclusion of competing political actors not just states, as well as its capacity to put Western and non-Western actors in a common analytic frame. By breaking out of the conceptual jails in which strategy has been incarcerated, I seek to reconnect International Relations to strategic thought from which it has become increasingly estranged.     

调度感知同步数据流建模

对流应用系统进行吞吐量分析需要将周期静态顺序调度建模到数据流图中,吞吐量分析效率依赖于数据流图的规模及建模时间。为了提高吞吐量分析效率,提出基于同构同步数据流图的调度感知同步数据流模型及相应建模方法。通过利用应用模型结构特征及周期静态顺序调度,可减少模型中的任务、边和初始符号数目;可以使用已有分析方法对模型进行吞吐量分析。实验结果表明,所提建模方法优于已有方法,可有效提高吞吐量分析效率。     

Explaining Cohesion in an Insurgent Organization: The Case of the Mizo National Front

Despite the prevalence of violent uprisings against the states, existing literature has produced a generalized explanation of the causes and onset of such uprisings ignoring crucial aspects of (non-state) armed group cohesion, such as their capabilities to manage intra-group tensions and rivalries. In this paper, I examine recent research in the field of civil conflict to understand the importance of investigating underlying constraints which can cause serious impediments to the capabilities of a state during the course of a war. The paper then focuses on the importance of internal strategic resources, such as pre-war and wartime sociopolitical networks in which insurgents mobilize, recruit new cadres and maintain intra-group cooperation, to suggest how it can contain the consequences of counterinsurgency operations and other state strategies on the internal cohesion of an insurgent group. A detailed case study of the Mizo National Front (MNF) in India demonstrates the argument’s plausibility.

非椭圆扩展目标联合跟踪与分类算法

充分利用目标尺寸和形状信息,提出了一种基于星凸随机超曲面模型(random hypersurface model, RHM)的非椭圆扩展目标联合跟踪与分类(joint tracking and classification, JTC)算法。将目标空间扩展状态建模为星凸形状,通过目标类别相关先验信息的矢量化建模,建立起其与目标瞬时扩展状态的关系,并在统一的贝叶斯滤波框架下,实现跟踪与分类的一体化处理;进一步对目标运动学状态和扩展状态单独进行建模,并通过构建扩展状态的似然函数,利用粒子滤波实现目标类别概率算式的递推处理。仿真结果表明:与基于椭圆形状的扩展目标JTC算法相比,所提算法能对尺寸相近、形状不同的目标进行准确分类,同时可改善目标状态的估计效果;与基于星凸RHM的扩展目标跟踪算法相比,所提算法能大幅提高目标状态的估计性能。
